Chemistry is in our everyday lives. When we wake up in the morning to when we see fireworks on 4th of july. People everywhere enjoy the fantastic explosions and the beautiful, bright, light displays of fireworks. Although, these spectacles are much more than just a form of entertainment. There is real chemistry packed into every firework. Everyone has complex formulas, and chemicals that react in certain ways with each other. There are about five different chemicals in a firework that work together to make a shape, color, and explosion size. The purpose of this topic is to explain how fireworks relates to chemistry.
How do fireworks relate to chemistry? A firework going off is just a big chemical reaction taking place. There are different chemicals

These chemical reactions all contain carbon, oxygen,potassium,nitrogen, sulfur, and charcoal.Each compound gives off a different color depending on how much heat is received and oxygen released.An easy way to get different color fireworks is to use a bunsen burner. These sodium compounds can also be called metal salts. Some examples are copper and barium gives a bluish green and calcium and strontium can make red fireworks.White contains magnesium, aluminum, and titanium; purple contains copper and strontium, orange has calcium salts, and yellow has sodium salts.Each chemical within each compound can be converted into light, heat, sound or kinetic energy; but when too much heat is given it can make a pollution or a explode on impact. In order to make fireworks you would need gunpowder and a heat source or these chemicals and a flame to ignite it. Gunpowder is a mixture of three substances; potassium nitrate, charcoal, and sulfur. Potassium nitrate can be classified as a decomposer and gas production due to the high temperature it heat it gives off when it reacts after touching oxygen. There are many different types of fireworks that form different types of reactions; they are rockets, missiles, flares or firecrackers, candles, and dynamite. The history of fireworks resulted around the chinese in around the 6th century for war purposes. They thought that this substance would be a good source of gas and firepower to their enemies. The most common example of fireworks is dynamite because when the string of dynamite that contains gunpowder is ignited by a flame oxygen is released and electron particles charge up and atoms to expand, then this will cause the product to
This smoke bomb lab helped me understand chemical bonding and reactions by starting from the very beginning with mixing the nitrate, sugar, and melted crayon. Mixing them formed a texture almost like powdery peanut butter with some liquid which was actually pretty interesting. The second chemical bonding I seen was that, once putting the solution in the tin-can and it started solidifying due to all the stuff we mixed together. It didn’t take long at all for it to start forming into a solid. When we went outside and lit the wick on fire showed the main chemical reaction throughout the whole experiment. The nitrate reacting with the lighted wick started a big fire in one of the groups cans but some of the other groups bombs didn’t get to light like it was supposed to and the wick just burned out. I was one of the groups whose bombs didn’t work properly. I think it’s because we didn’t put the wick in deep enough to our solution so when we lit it the fire just burned out before going into the solution.
Glow sticks get their “glow” when two chemicals are mixed together because of a chemical reaction. The chemical reaction is called Chemiluminescence. A Typical glow stick has a plastic tube with a smaller inner tube inside. There are three components, two chemicals and a fluorescent dye which accepts the energy and helps covert to light. There is more than one way to make a glow stick, but the most common uses a solution of hydrogen peroxide and phenyl oxalate ester along with the fluorescent dye. The hydrogen peroxide is in its own compartment away from the other two components until ready to use. The fluorescent dye is what determines the subsequent color of the glow stick when the chemical solutions are combined.
It is made mostly of copper carbonate. It can be crushed into a green powder. If this powder is heated it changes colour. A new substance has been made. The new substance is a black powder.
William Ramsay also discovered Neon. First of all, when Neon is charged with electricity, it only emits an orange-red glow. All other common neon colors are produced from different gasses. Those colors vary from green to yellow. The neon lights can also be colored by changing the color of the glass tubing that the gas and electricity are in.
The true rocket was born" (Brief History of Rockets). The earliest rockets were filled with gunpowder and used as weapons for war. They were also filled with many different chemicals and were thrown into a fire to make a loud explosion to scare off evil spirits. Goddard built small rockets and kept finding ways
All songs have a purpose, whether it is to calm, to hype, to vent, or to motivate. “Fireworks” is an empowering song written for people with low-self esteems. Katy Perry, the writer of “Fireworks”, used many effective tools such as pathos and symbolism in order to motivate her audience to jump over their personal hurdles.
There are hundreds of flames retardants and they are usually categorized according to their chemical composition. Their chemical composition affects their physical properties such as their color and smell, and their chemical properties
Fireworks are an established part of many festivities as entertainment, including Independence Day, community festivals, social gathering, and overall celebration, but also were used as weaponry by Chinese. (Helmenstine, Anne Marie) Fireworks need a source of combustible substance like metals. Metals are used in compounds or in their initial form to give color to fireworks. Therefore, they will glow when energy is applied. This occurs by 2 ways.
The ingredients that will be included are: dish soap, 30% hydrogen peroxide, potassium iodide, and corn starch. Adding the cornstarch to the mixture has a chemical reaction to the hydrogen peroxide. It will have light and dark patches due to the uneven placement of the cornstarch; it will have an uneven reaction. Which will then make it appear “glowing”. The fourth experiment is very similar when it comes to the ingredients the only thing that changes is that we are no longer using potassium iodide but we are using yeast instead. Also, since yeast is being used, we are adding in fluorescent dye to it so we can shine a UV (ultraviolet) light on it to see the reaction occurring. Using the dye under a light helps us observe the reaction between the dye and cornstarch. I had to replace the potassium iodide with yeast for a slow reaction and also so it is possible to use the dye. In both of these experiments the reaction is a massive production of foam. The hydrogen peroxide will be decomposed into water and by the oxygen by the iodide and/or the yeast. A substance called catalyst speeds up the
According to the chemistry book chemical reactions are,”the changing of substances to other substances by the breaking of bonds in reactants and the formations of bonds in products.” In other words, it is how chemicals react when they are mixed. How are chemical reactions used in detective work or in the show? A detective's line of work is widely involved in the use of chemical reactions.
A flammable gas can be triggered by a single spark. Class C fires are probably one of the most dangerous because if you are near them, you are exposed to potential explosions. That is right - a lot! This fire can randomly explode! Class D fires are metal fires.
For safety reasons, most Chinese cities banned firecrackers and fireworks in the year of 1990. From 1987 to 1993, during which time the explosions of firecrackers injured 2462 citizens in Beijing, the dangerous aspect of firecrackers has been taken into concern...
For example, copper produces blue fireworks, barium gives off green fireworks, and calcium produces orange fireworks. Fireworks have a really high melting point, this physical property kept firework to be safe, because if it burned easily in low temperature it can explode and cause safety issues. However, the fuel in the firework will only melt after it was light up by the fire, so we can control the time for it to explodes and go to safe area before
In fact, firecrackers can lead to significant casualties if people don't use it appropriately. In recent years, firecrackers are bannedb in some states in America. There are a total of 11 states that ban all types of firecrackers while some states only allow few types of firecrackers. Most leniently states such as Louisiana, Mississippi, Alabama, and Florida still allow all types of firecrackers ( Essoyan; Los Angeles Time ). The administration of some states has refused to allow the setting off of firecrackers during Chinese New Year celebration because these state governments believe that these explosives are too dangerous. Moreover, firecrackers have also been banned in China, after the firecracker storage area explosion incident.
